rl `his inventionrelates `.to an attachment especially designedfforuse in wells, cisterns or'qthe like/for purifying and aerating theI water contained therein. y v

The primary object ofthe invention is to provide atank to be located in the well or cistern, submerged in Vthe water contained therein, `whereby water :in the cistern is aerated, the y air' entering the tank at the bottom and Vpassing upwardly to the surface" of thevwater in thegcistern or well, while the tank refills with water.

Another object of the inventionk is to provide automatic'means for` admitting` watery to the tank, should the water in theltank be used therefrom'more` rapidly than the *water -could pass into the tank throught-he vusual.

filling opening thereof,

With the foregoing and other objects in view which will appear asthe description proceeds, the inventionresides in the cornbination and arrangement of parts and in the details ofv construction *hereinafter defk scribed and claimed, it` ybeing understood that changes in the precise embodiment of departing from the spirit of the invention.

Referring to the drawings: f n Figure, 1` is a sectional vv'iew'through the tank forming the `subject matterof the invention. i n' l Figure 2 is.l a transverse vsectional view therethrough.

y 3 3 of Figure l.

Referring to the drawing-in detail,`they tank is indicated generally by the reference,4

character 5, `the same being of any desired construction to meet the requirements of use. f

vThe upper wall vof the tank formed lwith i a filling opening'v to allow water to enter Theupper wall'v ofthe tank is formed with an opening'7 which is normally `closed by the.v cap 8, the opening 7 being relativelyk large so that access 4may be had to the inf l terior of the tankl to repair or replace the 'l v-valve members thereof.` `The discharge pipev .from the tank `is* indicated at.l 9 and has its i vlower end connected' with the tankat y10 p providing communication between the pipe l9 and tank 55o that when thepump struc- 1' the invention herein disclosed, may be made within the scope of what is -claimed without Figure 3 is a sectional viewtaken onl line",l

the tank as the water is used therefrom, it

isf'opjerated,iy Awater will be vdrawn from the tank 5 and into the pipef9V where th'esame .will bedischarged at the upp'er'end of the pipe 9.

Communicating with lthe tank `5 at the opkpositel endy thereof, isan` air inlet,r pipe 11 lthat has an inwardly'extended end'l2 sup'-k plied with a one-way kvalve member 12 which valve member allowsair under pressure to enter the tank` y5 through the pi eV 11. The upper end ofthe pipe 1 1v eXten s abovel the vcistern andy has connection with a suitable sourceof air supply to be forced into they tank, the, air escaping fromthe tank" at@ Aand passing upwardly aerating and "cleaning, the ywater in the cistern or well on lits upwardl passage. .p

Since the'tank 5 is submerged it will be pass through the ywater inthe cistern or well obvious that air passing from the tank mustr i in whichthetank 5 'is positioned, aerating l the water within the cistern or well;y l

Formed in the bottomv of -the tank l5, is an opening 13 which .is normallyclosed by kmeans of the ball valvel'tsupported at the l'lower endy of the valvey rod 15'whichhas connectionvwith the float A-16 so'that when the v water in the tank `1`5 rises above the float 16,v y Y thevalve14'willbeclosedfto prevent waterfrom entering the tank "5 'through the open* ing 13. v

\ Operated by the movement 'of the rod 15 isua ball Ivalve 17 thatY isdisposed within a ypredetermined level andjprevent water from entering the; tank through the opentot the tank 5 andoperates to close the opening 18,` when the waterI in the 4tank has reached l ois I 'ing 18. 'Ihis-ballvalvey 17 is carried at the free endof the rod 19,' which is pivotally@ l supported" by the larms' 20, the Hopposite end of ftherod'19 having pivotal connection with -Jl`ro1r'1fthe` vforegoing it vwill be obviousy vthat should the water `be withdrawn from l`vr the tankv 5 more rapidly than water could enter' through the filling opening 6, the float 16 would move downwardly, whenthewater in tank y5 reaches a predetermined level,

ytherebyVunseating the valves ltand 17 and` ,allowing waterto enterthe openings 13 and In the use fof the device,y air .is` yforced through .the pipeL lland entersv the-tank 5, aerating 'andfcleaning the same prior, to

its passage through the supply pipe 9 of the pump, also aerating and cleaning Water in cistern or Well prior to its entrance into tank 5.

What is claimed as neW is r In a device of the character described, a tank adapted to be submerged in a body of Water, said tank having an inlet opening in the upper portion thereof, said tank having an inletopening in the bottom thereof,
